A core component of applied educational and child psychology practice is the skilfulness with which practitioners are able to rigorously structure and conceptualise complex real world human problems. This is done in such a way that when they (with others) jointly work on them, there is an increased likelihood of positive outcomes being achieved for clients. The Problem-analysis Framework as discussed in this paper offers one way of working with such complexity which is grounded in a sound knowledge based in applied psychology. This paper provides further clarity on using the framework within applied practice. The authors were all trained in and use the Problem-analysis Framework and now work in many different types of applied settings within Australia, Iceland, New Zealand, Singapore and the United Kingdom. This paper illuminates important aspects of the problem-analysis approach itself for those currently learning it, as well as providing an aide-mémoire to those using it and those who want to develop their skills in this area.  相似文献

Steering higher education through the establishment of a “contract” between the state and the individual higher education institution is becoming an increasingly popular way of regulating the relationship between the two actors in the Nordic countries. This article addresses some theoretical foundations for this approach derived from principal/agent theory and analyzes the strengths and weaknesses of established contract arrangements in Finland, Sweden, and Denmark. The article discusses the potential of using such arrangements in relation to the efficiency/effectiveness dilemma. It is emphasized that trust is vital in solving this dilemma and that the balance between the need for public accountability, the efficient regulation of higher education, and institutional change must be given high priority in refining existing contractual arrangements.  相似文献

Designing collaborative multiplayer serious games   总被引:1,自引:0,他引:1  
The idea of Computer Supported Collaborative Learning (CSCL) is being investigated for more than twenty years. Since a few years, game-based approaches like video games for learning (Serious Games) offer new fields of application. The combination of game-based learning concepts and collaborative learning may enable new, game-based application areas of CSCL, like collaborative multiplayer Serious Games. Designing such games, however, is very challenging as it requires to take into account traditional single player game design concepts, concepts for multiplayer game design, and concepts for Serious Game design simultaneously. Only very few examples of such games exist today. In this paper we describe an approach for the design of game-based collaborative learning scenarios using multiplayer Serious Games. Our approach aims at combining design concepts from the fields of collaborative learning and (multiplayer) game design. Our approach takes into account the requirements of traditional single player games (fun, narration, immersion, graphics, sound), challenges of multiplayer games (concurrent gaming, interaction) and Serious Game design (seamless inclusion of learning content, adaptation and personalization). Furthermore, requirements of collaborative learning are considered, like group goals, positive interdependence, and individual accountability. Our design concept was used to create a collaborative 3D multiplayer game fostering collaborative behavior as a foundation for game-based collaborative learning in small teams. We performed a user study with eight gaming sessions and a total of 23 participants. Results showed that the game enables a collaborative gameplay and fosters collaborative behavior. This may allow us to use a game-based CSCL approach to combine the advantages of game-based learning with those of collaborative learning in future.  相似文献

The study by media psychologists of emotional communication in online bereavement still leaves many questions unanswered. Previous research has identified similarities as well as differences in emotion regulation patterns of children, adolescents, and adults (Döveling 2015a). Extending that research, this investigation of digitally mediated bereavement goes one step further by exploring additional types of mechanisms within the emotion regulatory processes of coping online. A total of 4 different bereavement platforms, used by mourners of differing ages and kinds of losses, from young children to widowers, were examined in a quantitative content analysis of online postings (N = 1036), generating insights into shared emotion regulation patterns and intimacy online. The findings highlight interpersonal empathy, irrespective of age of the bereaved or type of loss, but also disclose age-based differences in emotion regulatory processes. Implications for further media psychological analysis are laid out.  相似文献

Biomechanical differences in double poling (DP) between sex and performance level were investigated in female and male cross-country skiers during a classical race (10/15 km). Skiers were divided into faster and slower on basis of race performance: females faster (n=20), females slower (n=20), males faster (n=20), and males slower (n=20). Based on video analysis while DP in a flat section of the track, joint and pole angles at pole plant (PP) and pole-off, cycle characteristics and the use and coordination pattern of heel-raise (raise of heels from the ground to have a higher body position at PP) were analysed. Faster females and males had 4.3% and 7.8% higher DP velocity than their slower counterparts (both P<0.001). Faster males had 6.5% longer cycles than slower males (P<0.001). Faster skiers stopped heel-raise later than slower skiers (females: 2.0±3.4% vs. ?1.0±3.5%, P<0.05; males: 3.9±2.4% vs. 0.8±3.2% of cycle time in relation to PP, P<0.001). At PP, faster skiers and male skiers had a smaller pole angle and greater ankle to hip and ankle to shoulder angle with respect to vertical, resulting in a more distinct forward body lean. However, the majority of the differences are likely due to higher DP velocity.  相似文献

When athletes fail to perform at an expected level during an important moment, it is implied the athletes have experienced “choking“ (sudden decline in performance) under pressure.”. Researchers have reported that persistent left-hemispheric activation patterns occur when an athlete experiences considerable performance deteriorations under pressure. Researchers have also observed differences in brain activation patterns between left- and right-handed people on a variety of physical and cognitive tests, with the left-hemispheric activation more pronounced in right-handed participants. Purpose: The purpose of this study was to investigate whether athletes’ handedness may be linked to choking susceptibility (i.e., likelihood to experience performance decline under pressure). Method: Twenty right-handed and 13 left-handed experienced Australian football players completed 15 shot attempts, in both a low-pressure and a high-pressure condition. Both groups displayed equal state anxiety increases due to the pressure manipulation, indicating similar increases in anxiety in both handedness groups. Results: Differences were indicated in performance between the left- and right-handed groups during the high-pressure condition, with the left-handed group maintaining, and the right-handed participants declining, performance. Conclusion: Future electroencephalogram (EEG) research investigating this link may clarify the effect between handedness and choking.  相似文献

The jump throw is one of the most applied techniques in handball. Therefore, analyzing its underlying performance factors is important since they may provide a basis to adjust training interventions. Currently, the coach decides what needs to be improved in order to enhance the overall performance of an athlete. The aim of this study is to break down the performance factors in jump throws and to assign athletes to subgroups. This classification should allow athletes to benefit from the resulting group-specific training contents and may support a coach in deciding about the next steps in his training program. A total of 113 male handball players (age 15 ± 0.38 years, height 184.07 ± 7.1?cm, weight 74.83 ± 9.31?kg) participated in this study. From each athlete the standing reach height (SRH), the jumping reach height achieved with a countermovement jump (JRH), the maximal ball height achieved with a handball-specific single-legged jump and straight arm (BHJ), and the ball release height achieved in a jump throw (BHT) were measured. Performance factors were derived as differences between these measurements (JRH ? SRH = UJA for unspecific jump ability, BHJ ? JRH = SJT for specific jump technique, BHT ? BHJ = STT for specific throwing technique). A hierarchical cluster analysis was used to find groups of athletes based on the derived and scaled difference measures (UJA, SJT, STT). The dendrogram shows a clear distinction of four groups of athletes. Average values within each cluster reveal (A) one group with high UJA values, (B) one with low UJA values, (C) one with high SJT but low STT, and (D) one with low SJT but high STT. These results may be interpreted with respect to consequences for training because group (B) seems to benefit most from a general strength training while the properties of group (A), (C), and (D) recommend a focus on technical aspects of performance.  相似文献

Dinghy sailors lean their upper body over the windward side of the boat (‘hiking’) to keep the boat’s balance and maximise its speed. Sustaining the hiking position is essential for competitive performance and this study examined sport-specific differences of muscles relevant for hiking in elite sailors. Knee extensor muscle strength as well as trunk muscle strength, muscle endurance and muscle thickness were assessed in elite dinghy sailors (n = 15) and compared to matched, non-sailing controls (n = 15). Isometric extensor strength was significantly higher in sailors at 60° (+14%) but not at 20° knee flexion. Sailors showed significantly higher trunk flexor (but not extensor) strength under isometric (+18%) and eccentric (+11%) conditions, which was associated to greater muscle thickness (rectus abdominis +40%; external oblique +26%) and higher endurance for ventral (+66%) and lateral (+61%) muscle chains compared to non-sailors. Greater muscles thickness and the particular biomechanical requirements to maintain the hiking position may drive the increases in isometric and eccentric muscle strength as well as ventral and lateral trunk endurance. The current findings identified sport-specific muscle function differences and provide performance benchmarks for muscle strength and endurance in elite sailors.  相似文献
